Description
Technical field
The invention belongs to technical field of magnesium alloy surface treatment, relate to magnesium alloy chemical conversion-differential arc oxidation dark-colored ceramic membranes preparation method.
Technical background
Advantage such as magnesium alloy has light weight, thermal conductivity is good, thermostability is high, capability of electromagnetic shielding is good and damping and amortization is good, and aboundresources, be widely used, be described as " 21 century green engineering material ".But its solidity to corrosion is relatively poor, and surface hardness, wear resisting property also be difficult to the service requirements that reaches higher, and these have all restricted the development and application of magnesium alloy.Therefore, the development of the corrosion and protection technology of promotion magnesium alloy becomes most important.
Chemical conversion is handled and to be a kind of promptly convenient, economic, effective process for treating surface again at present, and provides good substrate for other means of defence such as coating, electroless plating etc. thereafter.Behind chemical reaction; form the bimetallic salt complex conversion film or the oxide film protection layer of one deck densification at Mg alloy surface; this stratification conversion film directly generates on matrix metal; form the structure of an integral body with matrix, with reach the solidity to corrosion that strengthens magnesium alloy and with the sticking power of other coated layer material.The corrosion protection ability of Chemical Converting Film of Magnesium Alloys is better than natural oxide film, can be magnesium alloy application substrate preferably is provided, and rete is very thin, contain a large amount of micro-map crackings, be convenient to the infiltration of coating in the coating process, realize conversion film and coating good binding, thereby improve the sticking power of application layer.
Differential arc oxidization technique claims differential arc oxidation or anode spark deposition again, is a kind of direct new technology at non-ferrous metal surface in situ such as Mg, Al, Ti, Ta, Nb, Zr growth ceramic layer.The recent two decades of this technology grows up on the anodic oxidation basis.
Early 1930s, G ü nterschulze and Betz have reported for the first time that under high electric field the spark discharge phenomenon appears in the metallic surface that is immersed in the liquid, and spark has destruction to oxide film.Discovered afterwards and utilize this phenomenon also can generate oxide film.After the seventies, states such as USSR (Union of Soviet Socialist Republics), the U.S., Germany all begin to have accelerated the research to differential arc oxidization technique.The electric source modes that is adopted changes afterwards sinusoidal ac and alternating-current pulse power supply into from the direct current or the unidirectional pulse power supply of beginning.The base material of oxidized processing mainly is aluminium, magnesium, titanium alloy.American-European countries is called anode spark precipitation (ASD) or spark discharge anodizing (ANOF) with the method for this formation surface film oxide usually.USSR (Union of Soviet Socialist Republics) and Russia then are referred to as differential arc oxidation (MAO).From document, U.S., moral, Russia three states independently develop this technology, and reference citation seldom each other.
Domestic research for differential arc oxidation started to walk since the nineties, introducing on the basis that absorbs Russian technology, began to move towards the practical stage with form wear-resisting, decoration coating, but will further expand its Application Areas, still had many work to do.The magnesium alloy differential arc oxidation correlative study document of publishing the earliest is ten years only so far, are the NaAlO of 10g/L as Xue Wenbin etc. in mass concentration
2In the solution MB15 magnesium alloy has been carried out the differential arc oxidation processing, obtained the oxide film of thickness above 100 μ m.Jiang Bailing etc. have carried out the differential arc oxidation processing to magnesium alloy MB8 in four kinds of different electrolytic solution of compound system that Phosphate Electrolyte, silicate systems, phosphate system and phosphoric acid salt and silicate are formed, and to the differential arc oxidation sample through the 96h salt-fog test, the result shows that the sample solidity to corrosion of handling in the compound system electrolytic solution is best.
Generally speaking, foreign study level integral body is higher than domestic, but external or does not domesticly all enter the large-scale industrial application stage now, understand and grasp this technology in depth, further enlarges its Application Areas, and much remains to be done.Along with the prominent advantages that people show day by day to the continuous exploration of differential arc oxidization technique and research and this technology, differential arc oxidization technique can extraordinarily come into one's own in the sufacing field, and obtains promotion and application widely in practice.
At present, differential arc oxidization technique is more single in the film color that Mg alloy surface forms, and mostly is the whiteware film.The single Application of Magnesium that limited greatly of color, aspect electronic communication product, decorating magnesium alloy surface become its widespread use the factor that must consider, as the magnesium alloy die casting of electronic product casing, must satisfy the human consumer to the multifarious requirement of surface color and polish.Therefore, chromatic research has great importance to ceramic membrane.And up to now, also chemical conversion and differential arc oxidation are not combined and prepare dark-colored ceramic membranes.
